ROLLER-SKATE.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed July 22, 1912. Serial No. 710,911.

To all whom it may concern Be it known that I, TnoMAs. SPAOIE, a

citizen of the United States, and a resident of Blue Island, in thecounty of Cook and State of Illinois, have invented a new and ImprovedRoller-Skate, of which the following is a full, clear, and exactdescription. This invention relates to roller skates, and has particularreference to a construction adapted to possess the maximum degree ofstrength and reliability, together with the minimum cost of production.

Another object of the. invention is to construct a roller skate adaptedfor the widest range of adjustability and yet in every position ofadjustment to maintain the maximum strength.

The foregoing and other objects of the invention will hereinafter befully described and claimed and illustrated in the drawings accompanyingthis specification in which like characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is a sideelevation with certain parts'in section; Fig. 2 is a front elevation;Fig. 3 is a vertical transverse section on the line 33 of Fig. 1; Figs.4 and 5 are detail views of parts of the hanger; Fig. 6 is a detail viewof the set screw retainer and guide; Figs. 7 and 8 are detail views ofparts of the anchor; Fig. 9 is asectional detail on the line 9-9 of Fig.1; Fig. 10 is a detail of one of the claws; and Fig. 1.1 is a sectionaldetail on the line l111 of Fig. 1.

Referring particularly to the drawings I show at 12 a main foot or soleplate and at 13 a heel plate, said plates being adapted to be coupledtogether by means of a rib or bar 1 1, and each of the plates is adaptedto be provided with a pair of rollers or wheels in any approved manner.

The bar 14 is substantially straight and rectangular in cross section,and is secured rigidly and permanently to the heel plate 13,longitudinal relative movement between the bar and heel plate beingprevented by means of a lug 13 fitting into a socket or cross groove 14in the upper surface of the bar. The front portionof the bar isadjustable with respect to the sole plate 12 and is adapted to beclamped in any posiadditional lugs 16 struck downwardly from the soleplate 12. As a means for securely clamplng the bar and sole platetogether in adjusted position, I provide a novel form of guide l7 shownin detail in Fig. 6, and

provided at its rear end with a T-head 18 adapted to pass rearwardlythrough the upper portion of the hole 15 and drop into the bottom ofsaid hole, bringing the lugs 18 into interlocking engagement with therear wall of the lug 15. When the bar 14: is introduced into the hole 15it will secure the head 18 of the guide 17 in said hole 15*. By thismeans the guide will be held from longitudinal displacement with respectto the sole plate. As an additional means for increasing the stabilityof the connection between the guide 17 and lug 15, the bottom of the lug15 is provided with a finger 15 adapted to be received in a hole 18 asshown in Fig. 1. The sides of the guide 17 consist of flanges 19extending upwardly parallel to each. other and of a distance apartsubstantially equal to the width of the bar 1-1, and the front end ofthe guide'is deflected upwardly with respect to its'rear end so as tocause the frontends of the flanges 19 to snugly embrace'the .sides ofthe bar 141. The flanges 19 serve also to house the nut 20 of the setscrew 21 passing through the bottom of the guide 17. upper end of thescrew impinges against the bottom of the bar, clamping the parts inposition. The nut 20 constitutes a substantial threaded means ofengagement for the screw threads, whereby the strain of the.

screw is relieved from the body of the guide 17.

Each pair of rollers 22 are mounted upon an axle 23 connected to ananchor 24, and

'eachanchor is in turn secured to the heel The and sole plates by meansof a hanger 25. Each hanger 25, as shown in this instance, comprises apair of braces 26 and 27 which serve not only to form a means forconnecting the anchor but also as part of the means for securing the bar1 1 to the respective foot portions 12 and 13. The brace 26 ispreferably formed with a pair of upper perforated ears 26 bent at anangle to the main portion of the brace and spaced to form a guide slot26 for the bar 14, and is furthermore provided at its lower end with aperforated ear 26". The brace 27 likewise is formed at its upper endwith a pair of perforated ears 27 and at its lower end with an ear 27.Adjacent the upper end the brace 27 is formed between the ears 27 withan upwardly projecting tongue 28 adapted to be received in a trans ersevertical slot 28 of the guide 17, whereby the bar 14 when lying betweenthe ears 27 will hold the guide 17 in interlocked relation with theupper end of the brace 27. The braces 26 and 27 through their upper earsare rigidly connected to the respective foot port-ions by means ofrivets or the like. Each of said anchors 2 1 comprises what may betermed a cradle 29 and a cap 30. The cradle is formed with a series ofperforated ears 31 bent downwardly from the main portion thereof and isalso provided with a pair.

of upwardly extending side flanges 32 having perforated ears 33. Theaxis of the holes in the ears 33 lies in a plane substantially at rightangles to the axis of the holes in the cars 31. The axle 23 passesthrough the ears 31 and is thereby held in position in any well known orapproved manner. The cradle between the flanges 32 is adapted to supportcushioning devices 34, which devices are retained in place by means ofdownwardly extending lips 35 of the cap 30, as shown in Fig. 9. The capis provided adjacent its ends wit-h transverse slots 30 each of which isadapted to receive an ear 33 of the cradle and one of the downwardlyextending ears of the hanger 25. A hinge pin 36 is passed through thealined holes in said ears below the cap 30 and through or between thecushioning means 3 1, whereby all of these parts just described are heldpermanently together but in a manner to provide any desired lateralrocking movement between the two parts of the anchor due to theresiliency of the cushioning means 34. The front hinge pin 36 is longerthan the rear corresponding pin and constitutes a brace for the clampscrew 37 having the usual threaded connection through right and leftthreads with the claws 38. The screw 37 is provided with a centralcircumferential groove 37 into which the front end of the pin 36extends, and the screw 37 is embraced by a clevis 38 which lies withinsaid. groove 37 and is connected with the pin 36 by a cotter 39. The pin36, therefore,

without departing from the spirit of the invention.

Claims for the skate roller supporting mechanism and the skate clamp arenot made herein but constitute the subjects matter for two divisionalapplications filed by me on December 28, 1912, Serial Nos. 7 39,064 and7 39,065, respectively.
